Re: Test Equipment Anonymous (TEA) : Discussion and Group Therapy Thread

In the USA you can buy rust stain remover containing HF at the hardware store :shock: Whink Rust Stain remover is 2% HF Suprisingly I found a UK seller https://www.repairingproducts.co.uk/product/whink-products-1291-rust-stain-remover-16oz/ The MSDS is appropriately amusing. If inhaled, on skin or ...

Bugger. There go some more hours.

Still a bit of a talking head, but at least the moving pictures are necessary, and the info content is relatively dense.

Just so. Arsine AsF 3 being another. My father was quite happy to bring home some conc HCl and iron sulphide in his coat pocket, and for me to stink out the kitchen by mixing them. He said he was frightened by HF, and wouldn't go near it, even at work. The "things I wouldn't work with" sub...

Re: Test Equipment Anonymous (TEA) : Discussion and Group Therapy Thread

Cerebus will probably know the most evil way of disposing of sodium. I have an acquaintance who is a top tier conspiracy wanker. I would probably dunk it in his fish tank. The most energetic would be to finely divide (i.e. grind) it in an inert atmosphere (argon say) and then rapidly combine the du...

Re: Better late than never department: Solartron 7075

Good news bad news. The bad news is that even with decent originals, some of the lines are very thin. The bad news is that the hugin panorama stitcher is proving to be a pain with photos of schematics. Even with many manually added homologous points, the straight parallel lines confuse it.

Chuck the sodium into a largish body of water. It will turn into sodium hydroxide as it rushes about and it may go boom. The sea would do. Chemistry teachers have caused serious accidents, by using a piece the size of a pea in a glass vessel full of water. I had a chemistry teacher who did the reac...

The Austin A30 & A35 had the "knob on the dash" but that was a bit of an outlier. What I was thinking about was something which was pretty much endemic in early 1950s Brit cars.DA8D3694-F0D2-4C44-A27A-64AA44BD798E.jpeg It was more "high tech" as it was self cancelling! My pa...

Yes indeed. I seriously considered it, and partially implemented it :) Has to be done within 2 years of the benefactor's death.

That enabled me to give sproglet some much needed money without any inheritance tax liability.

I also like my test gear to have as few menus as is practical - oscilloscopes especially should have knobs or switches for everything; I don't care if it makes the front panel look like a forest. Too many times on digital scopes I've tried to adjust something only to find I'm in the wrong menu so i...

I might be able to tolerate the DNR (oops :) ) being on a touchscreen; I'd have to see it to determine. The indicator controls must be in a fixed position. Makes me want to go and have a Tesla test drive. I'd be in the passenger seat so I could see how "well" an experienced user can/can't...
